Abstract:Open graded friction course (OGFC) is widely recognized for its environmental and safety benefits (e.g., water drainage and noise reduction). However, based on durability concerns, many states have limited the use of OGFC. The objective of this study was to evaluate the effectiveness of warm mix asphalt (WMA) additives, by-products (i.e., crumb rubber [CR]), and industrial fillers (i.e., Portland cement and fly ash) in enhancing the laboratory performance of OGFC mixes. To achieve this objective, a comprehensi… Show more
